☠️ Device Kill Switch — Disrupts and disables unauthorized surveillance devices. Use when you cannot physically locate or remove the device.
☠️
Ready
Select a kill method below
Kill Methods
🌊
Network Flood
Overwhelms device's WiFi connection with competing traffic
Medium
Creates massive WebRTC connection floods on the subnet. Cheap spy cameras with limited CPU cannot handle the load and drop their stream or reboot.
🔊
Ultrasonic Overload
Blasts frequencies that overload hidden microphone circuits
Medium
Plays a swept ultrasonic signal (17–22kHz) at maximum amplitude. Overloads the AGC (automatic gain control) circuits of hidden microphones causing them to clip, distort, or temporarily disable.
📡
Bluetooth Scanner Flood
Floods 2.4GHz band with BLE scan requests
Medium
Rapid Bluetooth scan requests create heavy 2.4GHz interference. Since most spy cameras operate on 2.4GHz WiFi, this degrades their signal quality and can force disconnection.
💀
FULL KILL SEQUENCE
All methods simultaneously — maximum disruption
Maximum
Runs all kill methods simultaneously: network flood + ultrasonic overload + BLE flood. Combined effect overwhelms surveillance devices on all vectors. Runs for 60 seconds.
🔑 Most Effective: Router Kill
Block Device at Router Level
The most reliable method. Even if you cannot physically find the device, you can permanently block it from your network at the router level.
Step 1 — Find the device IP
Run a Radar scan → check Device Radar Log in Logs tab. Look for unknown devices with low threat scores that you don't recognize.
Run a Radar scan → check Device Radar Log in Logs tab. Look for unknown devices with low threat scores that you don't recognize.
Step 2 — Access your router
Open browser → go to 192.168.1.1 or 192.168.0.1 → login with your router password (usually on a sticker on the router).
Open browser → go to 192.168.1.1 or 192.168.0.1 → login with your router password (usually on a sticker on the router).
Step 3 — Find connected devices
Look for: Connected Devices / DHCP Client List / Device Manager. Find unknown devices — note their MAC address.
Look for: Connected Devices / DHCP Client List / Device Manager. Find unknown devices — note their MAC address.
Step 4 — Block the MAC address
Find MAC Filtering / Access Control → Add the device's MAC address to the block list → Save. The device is now permanently blocked even if it's still physically present.
Find MAC Filtering / Access Control → Add the device's MAC address to the block list → Save. The device is now permanently blocked even if it's still physically present.
Step 5 — Change WiFi password
Go to Wireless Settings → Change WiFi password. This forces ALL devices including the spy camera to reconnect — and it cannot reconnect with the new password.

🏠 Homeowner Emergency Protocol
🚨 This Is Your Home — Immediate Actions
Step 1 — Call 911 NOW
Tell them: "I have discovered an active surveillance device in my home that I did not place there and did not consent to. I need an officer to document this." This is a criminal matter. Do not touch or move the device if found.
🚨 Call 911
Step 2 — Do Not Disconnect the Device
If you locate it physically — do NOT unplug it, move it, or touch it. Leave it exactly where it is. Law enforcement needs to document it in place. Use our Kill Switch to disable its transmission without touching it.
Step 3 — Secure Your Home
Change all door locks immediately. Change your WiFi password. Do not allow anyone into your home until police have documented the device. Who has had access to your home recently — contractors, guests, ex-partners, repair workers?
Step 4 — Generate Evidence Report
Generate a timestamped THRDi Shield evidence report right now. This documents the RF detection, signal strength, timing, and GPS location with cryptographic audit chain. This is admissible documentation.
Step 5 — FBI Tip (if local police do not act)
Unauthorized surveillance in a private residence is a federal wiretapping crime under 18 U.S.C. § 2511. The FBI investigates these cases.
🏛️ Submit FBI Tip at tips.fbi.gov
Step 6 — Know Your Rights
• 18 U.S.C. § 2511 — Federal wiretapping. Up to 5 years prison.
• 18 U.S.C. § 1030 — Computer fraud if device accesses your network.
• State laws — Most states have separate voyeurism/surveillance statutes with additional penalties.
• Civil lawsuit — You can sue for damages, legal fees, and emotional distress.

2-Story Triangulation
Mathematically calculates source location across both floors
Stand at each position listed, tap the button, and wait 3 seconds. After 4+ readings it mathematically triangulates the device location using signal decay physics. Works across both floors.
0 / 18 positions recorded
💡 How to use: You do NOT need to record all 18 positions. Record at least 4 — one in each corner of each floor you want to test. The result updates automatically after 4 readings and gets more precise with each additional reading. Stand still for 3 seconds when you tap each position.
🔭
Deep Passive Scanner
All hardware sensors simultaneously — most powerful detection
Uses every available sensor simultaneously: accelerometer, gyroscope, magnetometer, ambient light, barometer, microphone FFT, and multi-server network probe. Runs continuously and alerts instantly when signal exceeds threshold.
🏠
Room Grid Localizer
Pinpoints exact corner/wall — tap where you are standing
Stand in each part of your room and tap that position on the grid below. It records signal strength at that exact spot and builds a floor plan heat map. The red zone = device location.
TAP the zone where you are standing → it records signal strength there
0 zones recorded
💡 Method: Start in the center of the room. Tap Record. Move to NW corner — tap Record. Move to NE corner — tap. Move to SW, SE, then midpoints of each wall. The red zone tells you exactly which part of the room has the device.
🧱
Wall-by-Wall Scanner
Scan each wall — tells you which wall the device is on or behind
Ready
Stand with your back against each wall and tap the button. Builds a compass of signal strength by wall. The strongest wall = device is on or embedded in that wall or the corner where two strong walls meet.
📏
Height Scanner
Determines if device is floor, mid, or ceiling level
Hold phone at floor level, then waist, then above your head. Tells you whether the device is hidden low (inside furniture/outlet), mid-height (shelf/clock/frame), or high (smoke detector/ceiling).
📡 WiFi & Network Intelligence
🔍 Network Source Analyzer
Extracts IP address, network type, carrier info, and estimates how the device is getting its signal.
⚠️ How This Device Still Has Signal
📱 Method 1 — Built-in SIM Card (Most Likely)
Many professional spy cameras have their own cellular SIM card built in. They use 4G/LTE to stream video directly to the internet — completely independent of your WiFi. No WiFi needed at all. This explains why it's still active.
📶 Method 2 — Hidden WiFi Hotspot
The device creates its own WiFi network or connects to a previously saved network. If someone had access to your WiFi password before, the camera remembers it and connects automatically every time you're home.
🔋 Method 3 — Wired Power + Cellular
Device is plugged into a wall outlet (USB charger, power strip, or hardwired) giving it unlimited power. Combined with cellular — it can run indefinitely and never needs WiFi or battery replacement.
🌐 Method 4 — Neighbor or External WiFi
Camera is configured to connect to a neighboring WiFi network, a mobile hotspot left in range, or even an unlocked public network nearby. Does not need access to YOUR network at all.
🚨 Bottom line: A device being active without YOUR WiFi is a strong indicator of a professional-grade surveillance device with its own cellular connection. This is a serious situation. Generate an evidence report and contact law enforcement immediately.
📋 Recommended Search Order
1.Run Signal Heatmap — walk grid pattern, builds room heat map of signal strength
2.Use Hot/Cold Tracker — follow arrows toward the signal like a compass needle
3.At close range — use Micro Proximity — centimeter-level detection
4.Use Pulse Isolator — identifies the exact transmission pattern
5.Use Thermal Drain Scanner — finds device by battery/heat signature

Pulse Isolator
Identifies the device's unique transmission pulse pattern
Off
Hidden cameras transmit in a distinctive pulse pattern (typically every 33ms for 30fps video). This isolates that pattern from background noise.
No pulse data yet
🌡️
Thermal Drain Scanner
Finds device by its heat and power consumption signature
A transmitting hidden camera draws constant power and generates heat. When your phone is near it, the CPU load on your device measurably increases due to interference. This detects that effect.
—
CPU Load Interference
—
Drain Anomaly
Move phone slowly near all objects — watch for CPU spike
💡 How to use: Slowly move phone within 5cm of every object in the room — clocks, smoke detectors, chargers, vents, picture frames. Watch the CPU Load reading — a spike when near a specific object means that object is drawing extra power (transmitting).
📋 Physical Search Checklist
Check every item in this list — hidden cameras are most commonly found in these locations:
🎯 DIRECT PINPOINT MODE
Most sensitive detection available. Audio beacon + visual spike + vibration.
Walk slowly toward every object — it tells you HOT or COLD in real time.

Awaiting calibration…
Tap Start — stand still for calibration first
📋 Step by Step
1.Stand in the center of the room where the signal is strongest. Tap Start and stay still for 8 seconds while it calibrates.
2.Move extremely slowly — 1 step every 3 seconds. Walk toward one wall. Watch the bar and listen to the beep speed.
3.When bar goes orange and beep speeds up — you are getting closer. Stop. Note exactly where you are.
4.When bar goes red and phone vibrates hard — stop immediately. The device is within arm's reach. Don't move.
5.At that spot — hold phone 5cm from every object around you one by one. The bar spikes highest when you are directly over the device.
6.Check ceiling first — smoke detectors, vents, light fixtures. Then eye level — clocks, frames. Then low — outlets, power strips, USB chargers.

🚗 OBD-II Adapter Detector
Important: a phone cannot read your car's diagnostic port directly — that requires a physical Bluetooth or WiFi OBD-II adapter (ELM327-based, ~$10-20) plugged into your vehicle. This tool detects and connects to such adapters if one is present, and flags unknown/unauthorized adapters that shouldn't be there.
⚠️ Why This Matters
Unauthorized OBD-II adapters are sometimes used for covert GPS tracking or driving-behavior monitoring. If you find an adapter plugged into your OBD-II port (usually under the dashboard, driver's side) that you didn't install, that's worth investigating.
📜 Detected Adapters
